I once did a calculation for a NG, sci.military.moderated IIRC,
concerning the lethality of the hypothetical weapon given a beam pulse
energy comparable to the muzzle energy of a conventional handgun (about
700J).

The question I could not answer concerned its effect on the user of the
weapon. Would there be enough back scatter from the air at the muzzle
and along the beam path to seriously endanger the health of the firer?
